The first image ever transmitted on the web, first uploaded using a Mac.

When you think about the European Organization for Nuclear Research, or CERN, you probably think about all of their excellent particle smashing work, which recently culminated in the supposed discovery of the so-called ‘god’ particle, the Higgs Boson.

But twenty years ago this July, the researchers at CERN were responsible for another watershed moment, not in the history of physics, but in the history of the web: they put up the first ever image on the Internet. And they used a Macintosh to do it.
